KUNIsABURo NOMIYA, or BERKELEE'cALI'F'oRNIA.

. LAWN-SPRINKLER.

` V To all whom t may concern.'`

' resident of Berkeley, in the county of Ala` Be it known that I, KUNISABUR'O NOMIYA, a subject 'of the Mikado of "Japan, and a meda and State of California, have invented a new and Improved Lawn-Sprinkler, of

Whch the following is a full, clear, and exact description. j

My invention relates to lawn sprinklers of the revolving type.

An object thereof is to provide a simple and inexpensive lawn sprinkler which may revolve continuously in one direction or which may be, caused to, revolve forth and backl through predetermined angular distances.l j A further object of the invention is 'to provide a lawn sprinkler in which a sprinkling head is so arranged that it vwill deliver substantially the same amount of water near the sprinkling head as at a distance therefrom.

A still further object of the invention is to provide a lawn sprinkler which can be placed at different inclinations to the ground to be'sprinkled. n.

With the above and other objectsin view wsleeveV 12 so as to participate in the move- A the nature of which will more fully appear as `the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein all the views.

Figure 1 VisV a vertical, axial section through my device on line 1 1, Fig. 3; Fig.

2 is a horizontal, fragmentary section on line 2*2, Fig. 1; Fig. 3 is a horizontal section on line 3 3, Fig. 1; and Fig. l is an end elevation of the sprinkling head.

Referring tothe drawings, 5 is a cylindrical 'casing having a detachable head 6 at.

one end thereof. A gasket 7 is'4 interposed between the ends of the casing and the head 6 to prevent leakage therebetween. head 6 has an axial hollow projection 8 having an laxial opening 9 and a lateral opening 10. The casing has also a lateral opening l1 constituting the water inlet to the casing. which has means for securing it to a garden hose, and which is preferably diametrically oppositeto the opening 10 of Thel Specificatie? 0f Letters Patent. Patented June 13, 1916. Application led November 29, 1915. i Serial No. 64,0041 I i the projection 8. The projection 8 is rcduced externally at the end thereof to form a bearing for the end of a sleeve 12, one end y the casing 5. The lower end of the casing 1s formed bythe head 6. The upper end of the casing has an outer collar 13 surroundof which projects through the upper e'nd of ing thesleeve 12 to increase 'the bearing surface for the 4sleeve in theicasing 5. Said sleeve 12 has blades or vanes 14V within the casing 5. "f The water coming through Vtheinlet 11 of the casing is' ldirected against the vanes through. the medium of a gate vvalve 15 mounted to swing in the casing attheopen- -ing 11. yThe stemof the gate valvel projects through the top of the casing where ment ofthe sleeve. The delivery end 18 of the sprinkling head is convex, the upper portion of said end v18 being at a shorter radial distance. from its axis of rotation than .the

lower portion. The openings or perfora-j vtions 19 in said end 18 are' larger at the ,up-

per portion than at the lower portion, the

size of said openings decreasing graduallyy from the upper to the lower portion of the delivery end 18. Due to the curvature of the delivery end and to the various sizes of the openings, substantially the same quan tity of water is delivered near the sprinkler and at a distance therefrom. l'

To oscillate the sprinkling head within predetermined angulardistances in lieuvof continuous rotation thereof, a valve-operating member 20 vis mounted to rotate on the collar 13 at the 'top of the casing.A The valve-operating member has an extension 21 for engagingthe cranki 16 f the gate valve.l It has also a plurality of openings 22 each of which may be engaged by a p in 28, two of said pins being used, one to each side of' the head. As the water enters the casing, in the direction shown by the arrow in Fig. 2 it will cause the head to rotate in the direction shown by the arrow in Fig. 3

until thehead comes into engagement with y the'pin v23 seen in Fig. l, when the member 20 will be caused to swing onthe collar and move the gate valve l5 so as to switch the How to the other side of the casing, thereby reversing the rotary movement ofthe sprinkling head, which will then rotate in a direcyao tion opposite to the arrow indicated in Fig.

3 until it comes in contact with the corresponding pin 23, thereby causingla displacement of the member 20, which will Operate to be sprinkled, the base vof the device is provided with a sharp anchoring member or tongue 24 which is pivotally connected to the head 6 so that the casing can swing on y ,Y the tongue when the sameis secured.
